(Cl. 222-390) This invention relates to ejectors, and has been shown in connection with a shaving brush of the fountain type wherein the tubular handle is utilized as a chamber or magazine, and provision is made for conveniently feeding material from the handle through one end thereof, by means of the ejector mechanism of the present inven tion being located within the handle and actuated by appropriate manipulation thereof.

It is an object of the invention to provide for conveniently removing the ejector mechanism preparatory to refilling the handle and to enable the convenient replacement of such mechanism after refilling the handle without the necessity of adjusting its parts.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims, it, of course, being undersood that changes in the form, proportion, size and minor details may be made, within the scope of the claims, without departing from the spirit or sacrificing any of the advantages of the invention.

While the invention is illustrated and described as applied to a shaving brush, it is applicable and intended for use in cleaning and polishing brushes generally as well as in such devices as grease guns and the like.

In the drawings:

Figure 1 is a longitudinal sectional view.

Figure 2 is a sectional view on line 22 of Figure 1.

Figure 3 is an elevation of the removable ejector.

Figure 4 is a plan view of the ejector.

Figure 5 is a plan view of the gland 5 at Figure 1.

Figure 6 is a sectional view on line 66 of Figure 5.

The present disclosure is that of a shaving brush having bristles 1 carried by an annular sleeve 2, and a tubular handle or container 3 provided with a rear end 4 removably secured to the handle or container 3 in any suitable manner.

The brush head 2 is a tubular sleeve of appropriate shape having the butt ends of the brush bristles fixed securely therein and projecting from one end thereof in any well known or approved manner. The handle or container 3 has its front end portion received in one end of the sleeve 2 with its extremity abutting an interior shoulder 7 provided at a suitable distance within the sleeve. Within the same end of the handle or container there is a front end member 5 of a size to be inserted through either end of the handle or container and is mounted for rotation on the longitudinal axis of the container or handle. This front end member fits against the inner face of an inturned annular flange 8 provided at the front end of the container and is provided on its outer face with a central boss projecting a suitable distance beyond the handle. There is a passage extending centrally through the end member 5 and the boss for the extrusion of material which is to be contained within the part 3. An annular member 9 is fixed to the boss as by a press fit in a well known manner, and this annular member is threaded into the sleeve 2 and thus fixed there in. Thus, the inturned flange 8 upon the end of the handle or container 3 is positioned and held between the end member 5 and the annular member 9 providing a rotatable or swiveled connection between the handle and the sleeve 2.

When assembling the complete device the gland 5 is positioned within the handle with its boss projecting 2,695,118 Patented Nov. 23, 1954 through the open end thereof and the annular member 9 is pressed on said boss into contact with the inturned flange of the handle in such manner as to firmly hold said handle but to permit rotation thereof with respect to the said front end member. Thus, the handle, front end member and annular member 9 comprise a unitary structure with which the sleeve 2 carrying the brush 1 may be assembled by engagement of the threads of the sleeve and the threads of the member 9.

The inner face of the front end member 5 is provided with grooves 10, 10 disposed radially with respect to the open rear end of the passage through said front end 5 and boss thereon.

Within the hollow handle there is a follower 12 having its peripheral edge in frictional slidable engagement with the inner wall thereof. This follower is threaded on a screw-threaded rod 13 having arms 14 at one end and duplicate arms 15 at the opposite end there of. One of the arms 14 is shown as occupying one of grooves in the rear face of the front end member 5 so as to hold the rod 13 against turning, while the other arms 15 fit rotatably in a circular seat or socket 16 provided in the front face of the cap so that the latter may turn on or independently of the rod 13. One of the arms on the rod is intended to occupy one of the grooves so as to connect the head 5 with the rod for rotation of either member by the other. Grooves not occupied by an arm are open and in communication with the inner open end of the passage through the boss for the extrusion of material.

In order to fill the chamber in the handle the cap 4 is removed, and the rod 13 with its follower 12 is withdrawn through the open end of the handle. Whereupon the desired material is placed in the handle through the open end thereof and the ejector device replaced, with the member 12 disposed at what will be referred to as the outer end of the rod 13. The follower 12 will then be in the outer end portion of the handle and lying against the outer end of the charge of material in the handle. After thus introducing the material and the ejector into the handle, the cap or cover 4 is replaced, with the arms 15 received in the socket or seat 16.

To feed or force material from the handle into the brush, the sleeve 2 is held fixed and the handle 3 is turned upon its swivel connection between the member 9 and the gland 5. During this operation, the rod 13 will be held fixed by its arms 14 fitting within the seat 10 in the front end member 5, and thus the follower 12 will turn with the handle, due to its frictional engagement with the inner walls thereof, and thereby will be fed along the rod and against the rear end of the charge of material to press the same against the front end member and force some of the material through the passage 18 into the brush. To insure a satisfactory supplying of material into the interior of the brush, a flexible, preferably rubber, tube 17 is provided through the butt end portion of the brush, the tube being open at opposite ends so that material may be forced therethrough to the interior of the brush. Being flexible, the tube will bend or flex with the bristles, and not interfere with the manipulation of the brush in lathering the face.

After material has been exhausted or substantially exhausted, and the follower is at or near the inner en of the rod, to recharge, the cap or cover is removed, rod 13 carrying the follower 12 withdrawn endwise from the handle, reversed or turned end for end and returned to place through the open rear end of the handle, after a new charge of material has been placed within the handle. By reversing or turning the rod 13 end for end, the follower will be at the outer end of the rod in position to come against the end of the new charge of material in the handle. Thus, it is not necessary to rotate the follower on the rod and feed it back to the opposite end thereof preparatory to recharging. The arms 14 and 15 on the rod 13 are duplicates, so that either arm may be fitted in a seat 10, 10 to hold the rod against turning, while the other arm remains stationary in the seat 16 in the cap or cover 4 when turning the handle to feed material.

In operation, as heretofore stated, the sleeve 2 may be held and the handle turned, or the handle held and the sleeve turned. In the first instance, the frictional engagement of the periphery of the follower with the wall of the handle will cause the follower to turn upon the rod 13 which is held fixed by its arm 14 in one of the grooves 10, 10' in the end member. In the other instance the handle will be held, The rod 13 will turn with the front end member and sleeve, The frietio'nal engagement of the periphery of the follower 12 with the fixed handle will hold the follower from turning and the rod will turn in the follower and the latter will be fed bodily along the rod. V

In the appended elair'ns' the end of the device provided with the bristles is referred to as the forward end and the opposite end is referred to as the rear.-

It will be noted that the radial arms on the threaded rod 13 together with the grooves 10 and 10 constitute a slip joint detachable connection between the front end member 5 and the threaded rod which may be conveniently disconnected by pulling the rod out of the rear end of the container 3 and as readily engage with the end member 5 merely by thrusting the rod inwardly through the rear end of the container.
